Dear R-Users,
ade4TkGUI is a new package available on CRAN. It implements a Tcl/Tk
graphical user interface (GUI) for the ade4 package.
Only the most basic functions of ade4 have a GUI in this first
version : classical one-table data analysis methods (PCA, COA,
MCA, PCO, etc.), one table with groups of rows (BGA, WGA, DA),
and two-tables analysis methods (Coinertia analysis, CCA, PCAIV).

One of the benefits of using ade4TkGUI is the centralized graphical
display of the dudi objects created by ade4. A dudi is a list with
many components http://pbil.univ-lyon1.fr/ade4html/dudi.html
The GUI presents a window in which the user can click on dudi
components to get predefined graphical displays :

Another benefit is for complex functions, and particularly graphical
functions that have many parameters. For example, the s.class function
has 27 parameters : http://pbil.univ-lyon1.fr/ade4html/s.class.html
In this case, the GUI makes it much easier to try various graphical
options : http://pbil.univ-lyon1.fr/JTHome/s.class.jpg
ade4TkGUI also contains a factor map exploration function, written by
Stephane Dray. This function allows dynamic operations like zooming,
panning, and identification of points by searching on labels on the
factor maps : http://pbil.univ-lyon1.fr/JTHome/explore.jpg
Current version (ade4TkGUI_0.1-4) depends on ade4_1.4-2, and the
dynamic factor map exploration function depends on tkrplot. Future
versions will add GUIs for more advanced ade4 methods, like ktables
analysis methods, or spatial methods, and for more graphical functions.
